Tesla is rolling out more Model Y prototypes for testing and we are getting to see the new electric crossover in new colors, including now a beautiful new bright red prototype spotted at Gigafactory 1.

Earlier this month, a Model Y prototype was spotted being tested around Tesla’s headquarters in Palo Alto and since then, there has been a more steady stream of Model Y sightings.

This week, we reported on a bunch of Tesla Model Y vehicles with new wheels spotted on a carrier near the factory and later, a beautiful new Model Y Midnight Silver prototype was spotted in Fremont.

The only in-flight beverages on the 11-seat private jet were bottled water and a genetically modified bacterial slurry designed to prevent the worst effects of hangovers.

A handful of passengers on the short evening flight from Hawthorne to the edge of the Mojave — venture capitalists, a man with a mushroom-based manufacturing company and this reporter — downed the mixture. The pilot, along with two senior SpaceX engineers, politely declined.

At the Apple Valley Airport, a helicopter waited to take us beyond a far ridge, farther from civilization. Miles from paved roads were two tents, a ring of shipping containers and an “H” painted on the dirt marking a makeshift helipad.

Tesla’s air filtration system with “Bioweapon Defense Mode” is proving useful for the owners affected by the current wildfires in California.

Watch an owner using the system while going through a hellish-looking road with scary air quality.

With the Model X, Tesla put a lot of effort into developing a more powerful air filtering system in order to not only contribute to the reduction of local air pollution with electric vehicles, but also to reduce the direct impact of air pollution on the occupants of its vehicles.

Researchers at TU Delft have developed a new supercompressible but strong material without conducting any experimental tests at all, using only artificial intelligence (AI). “AI gives you a treasure map, and the scientist needs to find the treasure,” says Miguel Bessa, first author of a publication on this subject in Advanced Materials on 14 October.

Miguel Bessa, assistant professor in and engineering at TU Delft, got the inspiration for this research project during his time at the California Institute of Technology. At a corner of the Space Structures Lab, he noticed a satellite structure that could open long solar sails from a very small package.

A team of researchers from the Universitat Politècnica de València (UPV) and the Université Paul Sabatier-Toulouse III (France) have developed a system that is capable of managing all traffic in a city, which will help to prevent traffic jams while reducing the driving times of vehicles and pollution levels. The system has been designed for autonomous vehicles and includes a route provider service capable of forecasting the present and future density of traffic in the city. It also takes that information into account when choosing new routes. The work has been published in Electronics.

Unlike existing systems that can suggest alternative routes depending on the bottlenecks at a certain time, the new system makes it possible to find out the present and future density of in the entire metropolitan area, and controls traffic as a whole, aiming to minimize or totally eliminate . In addition, it allows including different criteria—environmental, atypical situations, accidents, etc.—to dynamically provide advice about routes.

“Our proposal makes it easier for authorities to restrict or eliminate traffic in a certain area during the time period they find appropriate. For example, reducing traffic next to schools during the entry/exit hours, or in areas where ambulances circulate or an accident has happened, etc.,” explains Carlos Tavares Calafate, researcher at the Networking Research Group-DISCA of the UPV and coordinator of the work.

Elon Musk gave another hint about the Tesla Pickup truck design, which he now calls ‘Cybertruck’. The CEO says that it looks like ‘an armored personnel carrier from the future.’

The CEO shocked some when he said that the Tesla Pickup Truck will have a ‘really futuristic-like cyberpunk Blade Runner’ design without explaining what that meant other than saying that ‘it won’t be for everyone’.

On top of the comments not being clear, Musk didn’t really help anyone when he released a very cryptic teaser image for the pickup truck during the Model Y unveiling earlier this year.

Physicists and materials scientists have developed a compact optical device containing vertically stacked metasurfaces that can generate microscopic text and full-color holograms for encrypted data storage and color displays. Yueqiang Hu and a research team in Advanced Design and Manufacturing for Vehicle Body in the College of Mechanical and Vehicle Engineering in China implemented a 3D integrated metasurface device to facilitate miniaturization of the optical device. Using metasurfaces with ultrathin and compact characteristics, the research team designed optical elements by engineering the wavefront of light at the subwavelength scale. The metasurfaces possessed great potential to integrate multiple functions into the miniaturized optoelectronic systems. The work is now published on Light: Science & Applications.

Since existing research on multiplexing in the 2-D plane remains to fully incorporate capabilities of metasurfaces for multi-tasking, in the present work, the team demonstrated a 3D integrated metasurface device. For this, they stacked a hologram metasurface on a monolithic Fabry-Pérot (FP) cavity-based color filter microarray to achieve simultaneous cross-talk, polarization-independent and highly efficient full-color holography and microprint functions. The dual function of the device outlined a new scheme for data recording, security, encryption and information processing applications. The work on 3D integration can be extended to establish flat multi-tasking optical systems that include a variety of functional metasurface layers.

Metasurfaces open a new direction in optoelectronics, allowing researchers to design optical elements by shaping the wavefront of electromagnetic waves relative to size, shape and arrangement of structures at the subwavelength. Physicists have engineered a variety of metasurface-based devices including lenses, polarization converters, holograms and orbital angular momentum generators (OAM). They have demonstrated the performance of metasurface-based devices to even surpass conventional refractive elements to construct compact optical devices with multiple functions. Such devices are, however, withheld by shortcomings due to a reduced efficiency of plasmonic nanostructures, polarization requirements, large crosstalk and complexity of the readout for multiwavelength and broadband optical devices. Research teams can therefore stack 3D metasurface-based devices with different functions in the vertical direction to combine the advantages of each device.

Porsche and Boeing are teaming up to build luxury, electric-powered vertical takeoff and landing (VTOL) aircraft for rich people to fly above traffic-choked cities. They are the latest companies to announce intentions to explore the risky and potentially dangerous urban air mobility market.

Porsche and Boeing have signed a nonexclusive memorandum of understanding, which means they will look for ways to work together, but they aren’t locked into a binding agreement. As part of the partnership, the companies say they will “create an international team to address various aspects of urban air mobility, including analysis of the market potential for premium vehicles and possible use cases.”

The word “premium” would seem to indicate that this won’t be a “flying car” for the masses, which is fair considering we’re talking about Porsche here. Many companies interested in creating a network of electric flying taxis have stretched credulity by insisting that people at all income levels will be able to afford to purchase tickets. But given the costs associated with creating an infrastructure to support electric vertical takeoff and landing (eVTOL) aircraft, including landing pads and charging stations, it seems clear that it will be marketed toward the very wealthy — at least to start.
